The backgrounds in the Homeworld @ mod are generated in Space Engine, a program that itself allows modding. In one of those backgrounds a planet is visible, a Taiidani planet named Nirgal, a mostly ocean planet with a dramatic moon/ring system. We’ve put together a custom galaxy with a few set star systems in it, to better hit what the mod needs for skyboxes and to have important locations persist through space engine version changes. That’s led me down a rabbit hole to doing custom textures for a planet in one of those systems, not so much because the mod needs it as because it’s an interesting challenge.
Practically speaking there’s an unlimited amount of time I could pour into refining things, as the surface of a planet is a vast canvas, but for now I’ve decided to call it done and move on.
While this galaxy was made for internal use, if you want to it out I’ve made the current version available for download. Be warned, it removes the milky way galaxy.
Named systems present in the addon to date include Higaara, Kharak, Kostenki, and Nirgal. These systems are largely procedural in nature, save for Nirgal, which is the planet with the custom textures.
